Matt... buy a Concord RG-25XC from your favorite supplier. It's covered under STC# SA01250WI and is a direct replacement in the Grumman plastic battery holder.
Call Concorde Battery at (800) 757-0303 for STC details. They will usually send you the paperwork for your Cheetah serial number for no charge, then talk your friendly AI into filling a Form 337 for you.
Since it's sealed, you don't have to worry about the plastic hose venting outside any more...
Did this on my Tiger, I couldn't see the need for wet acid in the engine compartment.
